Dropbox power up doesn't work

[Marco Viale]

I'm business class user, I'm a dropbox advanced user so I have all the rights to activate power ups in Trello and to use Dropbox.

When I tried to link a Dropbox folder to a card in Trello the system returned me de message "impossible to send the message to host site" and it doesn't link the folder to card.

What can I do?

As a first step, I would check if any firewall or security app (extension in the browser) might be causing the issue preventing from within Trello connecting to Dropbox: https://help.trello.com/article/736-troubleshooting-browser-issues-with-trello

If that does not help, we'd recommend reaching out to our support team via trello.com/contact and include the error log of the browser. You will find instructions on the page mentioned above.
